To all whom it may concern: 4

Be it known that I, REGINALD A. F ESSEN- DEN, a citizen ofthe United States,- residing power year, thus v and can be used method may which this can be' accomplished' comer-- means at presentknown is the storage battery. This 15, how-,

cially. The most efficient ever, only useful on a small scale or as means of smoothing out sudden fluctuations, in power because on a large scale the cost of storing power with a st;- ge battery is more than the cost of produc- .-g'it by steam engine. i

I havediscovered a method of storing'up' energv at a cost including interest and depreciation not to'excced $3.00 per permitting "power derived from natural sources to bestored and furnished at a cost competing with present steam and gas engine plants. Moreover the method, in spite of the fact thattheobject is one greatly needed and long sought for unsuccessfull is 'of the utmost simplicity for stationaryplants 111 any place or country and thus the problem so-important to mankind-of storing upthe energy derivable from natural sources lscompletely and commercially solved.

-The drawing which accompanies and forms apart of this specification illustrates' one arrangement'of apparatus whereby my be realized in practice.

In the drawings,"the figure shows an apparatus for using wind power and for con; serving all the power where the'natural' circumstances are notfavorable on account of anintervening height of land lying between two reservoirs which are so far apart that a mechanical drive isnot possible front a System of Storin Upon the. of the series type.

- two reservoirs at Windmill located near one reservoir to a pumlplocated near the other. In this case the iquid circulates over such intervenin elevation. and use is made of What I call an electrical siphon. 5

In the particular drawing selected for more fully disclosing my. invention, 25- and 2.? are 'dynamos'c'apable of operating either as motors or generators and arepreferably 24:, 26 are pumps, 28,29 are turbines, 30

.In operationthe Windmill 33 drives the dynamo 32, the electric generator 27 being connected to act. as a'motor and drive the pump 261 Water is therefore pumped from the lower reservoir 34 into the upper reservoir 35. This water is' caused to pass through the turbine 28 and to drive 'the 31 is an electric transmission -l1ne, 32j is a ynamo operated by the winddynamo25' as a generator thereby restoring some of the power to the system. When it is desired to utilize the power the generator is caused to act as a motor and drive the pump 24 so as to cause water'to flow through the pipe 30. This water in des'cendingis thus furnishing current to the line and at the same time operating the dynamo 25 as a wound they automatically regulate each other and in this way water can be trans- As the two dynanios are series,

I do not limit myself to the specific apparatus shown, inasmuch as many modifications may be made therein without departing from the I c1aim:-- l.
